La présente invention a donc pour objet d'améliorer l'organe de pression en matière plastique d'un mécanisme de direction à crémaillère, de telle sorte qu'il conserve ses bonnes propriétés d'amortissement pendant une longue période, tout en présentant une faible usure. De ce fait, une pression superficielle la plus constante possible de l'organe de guidage dans l'alésage du carter doit être prévue. En outre, l'organe de pression est réalisé à peu de frais et il est d'un montage facile.  It is therefore an object of the present invention to improve the plastic pressure member of a rack-and-pinion steering mechanism so that it retains good damping properties for a long time, while having a low wear.
